"Morne Diablotins, a relatively unknown volcano in northern Dominica, is the largest and highest on Dominica and the second highest peak of the Lesser Antilles. A complex of at least five coalescing lava domes forms the broad summit of roughly 1430-m-high Morne Diablotins, and other domes are found to the SE. Pyroclastic-flow deposits emplaced about 22,000-40,000 years ago, known as the Grand Savanne Ignimbrite, extend in five radial tongues around the volcano as far as the coast. Precolumbian block-and-ash flow aprons on the NW flank are relatively unmodified by erosion. No historical eruptions are known from Morne Diablotins, although numerous hot springs, both onshore and submarine, are found near Glanvillia, on the NW flank. Severe earthquake swarms in 1841 and 1893 originated either from Morne Diablotins or Morne aux Diables to the north." -Smithsonian Volcano Archive
